EXTENSION SHOE-LAST.

SPECIFICATION forming part of Letters Patent No. 480,596, dated August9, 1892.

Application filed July 13, 1891.

To on whom it may concerni- Be it known that 1, JAMES HOMER LIVER- MORE,of Port Townsend, in the county of J eflerson and State of Washington,have invented a new and useful Improvement in Extension Shoe-Last-s, ofwhich the following is a specification.

My'invention relates to that form of last shown, for instance, inpatents to Leighton, Nos. 407,080 and 407,081, in'which a heel portionis provided with an extensible toe or sole portion which is madereversible and is also adapted to be extended more or less, according tothe size of the shoe, the same being especially designed for use inrepairing.

It consists in the peculiar construction and arrangement of the parts,as will be hereinafter fully described.

Figure l is a perspective view of the entire last. Fig. 2 is aperspective view of the detached toe portion. Fig. 3 is a perspectiveview of the connecting-bar; Fig. 4, a perspective view of the heelportion, and Fig. 5 a view of the set-screwfor connecting the parts.

In the drawings, A represents the heel portion of the last, which ismade, preferably, of cast-iron and is formed hollow with a crossbar anear its front end and a screw-holeb in the instep portion, whichscrew-hole is threaded to receive a set-screw. o. Extending through theopen front end of the heel portion and resting upon the cross-bar a is aconnectingbar D, also made of metal. This connectingbar has at its frontend a downwardly-extended T-shaped head 6 and on its upper face has aseries of graduations g and just back of these a series of screw-seats fto receive the point of the set-screw in the various adjustments.

B is the detachable toe or sole portion, which is also preferably madeof metal and has in its center an elongated slot cl, with raised edges.The opposite ends of this portion B are made substantially alike, exceptthat one is broader Serial No. 399,418- (No model.)

than the other to fit into the different styles of toe. Through the slot(1 is passed the T- shaped head 6 of the connecting-bar D, the part Bbeing for this insertion turned at right angles to the bar, so as to letthe head e pass through the slot the long way, after which the part B isturned back into alignment, which causes the ends of the head e to finda bearing against the under side of the portion B. I

The rear end of the connecting-bar D extends into the heel portion aboveits cross-bar a in a socket which closely fits the same, and into one ofthe seats f the point of the screw 0 is turned to lock the parts tightlytogether, so that they cannot slip apart or become dlsplaced. VVherethegraduations show beyond the front end of the heel portion the size ofthe shoe isindicated. With this construction it will be seen that thelast may be adapted to any ordinary size of shoe, and either end of thetoe portion may be used by simply reversing that section.

Having thus described my invention, what I claim as new is- 1. In anadjustable shoe-last, the combination of the reversible toe-section B,having an elongated slot d, with raised edges, and the connecting-bar D,having an offsetting or downwardly-extended T-shapedheade,adapted to bepassed through the slot 61 when turned at right angles and to look underthe same when turned into alignment, substantially as shown anddescribed.

2. The connecting-bar D, having the T- shaped head 6, graduations g, andscrew-seats f, in combination with the heel portion A, having cross-barCL and set-screw c, and the reversible toe portion B, having the slot d,substantially as shown and described.
